Definitions

  • the present invention relates to a seal for bearings and especially such a seal including means which enable the measurement of the rotational velocity.
  • a seal for bearings especially roller bearings comprising a sealing means including a sealing element made of an elastomer and a casing means made of metal, said sealing means comprising a first sealing surface forming the annular surface of a hole, in which hole a shaft is intended to be positioned and thereby statically seal against said first sealing surface, which thereby is provided for acting as a carrier for the sealing means in relation to said shaft, and a se­cond sealing surface having an outwardly directed seal­ing lip forming a part of said elastomer element, said casing means comprising a portion which at least sub­stantially forms a cylindrical casing having an inwardly directed surface which is provided for dynamically seal­ing against said second sealing surface, and an outer casing surface which is provided for the insertion into a seating of a hub surrounding said shaft.
  • a seal of the above described kind is often used in machines where it is also desired to measure the rota­tional speed of the part which rotates by means of the bearing.
  • this disc is produced in a qualified manner in order to fulfil the high demands concerning permissible variations. Furthermore, this disc has to be attached to the rotating part in a pre­cise manner, in order to make its function reliable together with the sensor means.
  • the latter device involves an improvement in relation to prior art devices it also includes some disadvantages. Firstly, it involves the disadvantage that the production thereof has to be carried out in­cluding one further kind of production unit, i.e. wel­ding, which make the production more complex and expen­sive. Secondly, the device is still not integral with anyone of the other parts and accordingly it therefore can loosen and fall off.
  • the object of the present invention is to remedy the above mentioned deficiency concerning known prior art.
  • a seal of the above mentioned kind wherein said casing characterised in that said casing has a main part of sheet metal with a radial cross section generally in the shape of a Z, of which the intermediate portion forms said cylindrical casing; said intermediate portion at one of its ends has an inwardly directed portion in the shape of a disc, which inner diameter is larger than the diameter of said shaft; and that said intermediate portion at its other end is provided with a second disc which extends outwardly and is provided with a large number of recesses, preferably in the form of perforations, which between each other form teeth for the use as a rotating means in order to affect a sensor, e.g magnetically, as the casing rotates together with the hub.
  • FIG. 1 there is shown a principle arrangement of a seal 1 in accordance with the invention.
  • the seal 1 is attached to a hub 12, which is rotatably arranged on a shaft 5 by means of a roller bearing 20.
  • FIG. 2 there is shown a cross section of a seal 1 in accordance with the invention.
  • the seal 1 is formed of two basic means, a sealing means 2 and a casing means 3.
  • the sealing means 2 has two main functions.
  • the first main function is to statically seal against the shaft 5. This first sealing function is achieved by an annular inwardly directed, first sealing surface 4. This part of the sealing hinders grease from the bearing 20 to escape between the inwardly facing surface 4 of the seal 2 and the shaft 5.
  • the second main function of the sealing means 2 is to hinder grease, or similar fluids, to escape between the hub 12 and the outwardly facing surface 6 of the sealing means 2.
  • the second sealing surface 6 is achieved by a sealing lip 6 which dynamically seals against an inward­ly directed surface 8 of the casing means 3.
  • the casing means 3 is made of an annular sheet metal part, which has a radial cross section generally in the shape of a Z.
  • the intermediate portion 7 of the casing means 3 has an outwardly directed surface 9 which is to be fitted within the hub 12.
  • the inwardly directed surface 8 of this intermediate portion 7 forms said sealing surface 8 of the casing 3.
  • the intermediate portion 7 has an inwardly directed portion 11 which inner diameter has to be larger than the diameter of the shaft 5.
  • an outwardly extending portion 10 which is provided with a number of recesses 13.
  • the recesses 13, e.g. perforations it is possible to measure the rotational speed of the hub 12. This is effected by positioning sensor means (not shown) to a stationary part of the machine, e.g. the shaft 5, in such a position that it can sense the rotational speed of the recesses. This can for example be achieved by using a magnetically sensing device which transmits a pulsation for each passing recess. By counting these pulsations, the distance between the recesses and make a time comparison it is possible to define the actual rotational speed.
  • FIG 3 there is shown a preferred embodiment of a sealing means in accordance with the invention. Apart from the sealing function concerning liquids this seal also provides for sealing against dust. This sealing function concerning dust is achieved by arranging at least one more sealing lip 16 extending outwardly and which lip dynamically seals against said inwardly directed surface 8 of the casing 3. Furthermore it is shown that the sealing means 2 includes a L-shaped member 17, 18 which shall act as a supporting member for the elastomer portions of the sealing means 2. This, however, is optional.
  • the casing means 3 of the seal in accordance with Figure 3 is made of two members. Firstly it comprises a Z-shaped member 7, 11, 13 formed in the same way as the one shown in Figure 2. Further it has a second casing member 14, 15 which is L-shaped. This L-shaped member has a cylindrical portion 14 of which the inwardly facing surface forms said sealing surface 8 of the casing 3. The second leg 15 of the L-shaped member is inwardly directed and forms an elongation of the out­wardly extending disc 10 of the Z-shaped member.
